Recommendations and selection criteria
Before choosing a desktop tool, first of all, you need to determine for what purposes it will be used.
It is worth paying attention to the following characteristics:
- the power of revolutions should be maximum. By pressing the object on the sharpener, the turnover rate is significantly reduced. On a small machine, it is quite difficult to process a dimensional tool;
- a manual machine is much easier to maintain than an electric one;
- the heavier the machine, the safer it is. When choosing, you should pay attention to the weight of the installation. Massive and oversized equipment is more stable, so work on it will be of better quality and less dangerous;
- the turnover shaft must be correctly positioned in relation to the center. Incorrect installation can lead to grinding of the sharpener against the protective walls, rapid wear and poor processing of tools. This is an important point to pay attention to first;
- Safety is the main criterion that should not be forgotten. Before starting work, make sure that the unit is installed securely and grounded. In the set of new 2020 models, the machines come with a protective glass made of transparent plastic. If it is absent, then it is worth using glasses or a mask.
Universal sharpening machine
In 2020, completely new universal grinding and grinding machines are presented on the market, which are designed for sharpening various tools for the home, as well as industrial use.

A tool compartment is built into the machine body, where you can store grinding wheels, leather wheels, holders and setting templates that come with each model.
